[0001] This application relates to the field of headphone technology, and more particularly to a headphone and headphone assembly. Background Technology

[0002] In related technologies, noise-canceling headphones typically have a microphone hole to collect ambient noise. This microphone hole is usually machined after the outer shell is formed, resulting in higher manufacturing costs. Summary of the Invention

[0003] In view of this, the embodiments of this application aim to provide an earphone and earphone assembly to improve the situation where the cost of the pickup hole is high due to the subsequent machining process.

[0004] To achieve the above objectives, one aspect of this application provides an earphone, comprising:

[0005] The outer casing has a sound inlet inside.

[0006] A sound-generating unit and a sound-receiving unit are disposed within the housing. The sound-generating unit is disposed on the side of the sound-receiving unit near the concha cavity, and the sound-generating unit is electrically connected to the sound-receiving unit.

[0007] The outer shell has an integrally injection-molded first pickup hole, a pickup channel, and a second pickup hole. The first pickup hole and the second pickup hole are located on opposite sides of the outer shell along a first direction for connecting to the external environment. The pickup channel connects the first pickup hole and the second pickup hole along the first direction. The sound inlet is located on one side of the pickup channel along a second direction for connecting the pickup channel and the sound receiving unit. The pickup channel is isolated from the sound generating unit. The first direction intersects the second direction.

[0008] In some embodiments, the pickup channel has an opening on the side away from the inlet along a second direction, and the earphone includes a seal that is connected to the housing and closes the opening to isolate the pickup channel and the sound-producing unit.

[0009] In some embodiments, the seal is a flexible element.

[0010] In some embodiments, the seal is adhered to the inside of the housing.

[0011] In some embodiments, the pickup channel includes a first channel along a first direction and second channels disposed on opposite sides of the first channel along the first direction, wherein one of the second channels connects the first channel and the first pickup hole, and the other of the second channels connects the first channel and the second pickup hole, and along the second direction, the size of the first channel is larger than the size of the second channel at least at its junction with the second channel.

[0012] In some embodiments, the first channel has an opening on the side away from the sound inlet along the second direction, and the side of the first channel away from the opening along the second direction has an inner wall, the angle between the inner wall and the cavity wall of the first channel along the first direction being greater than 90°.

[0013] In some embodiments, the first channel has an opening on the side away from the sound inlet along the second direction, and the side of the first channel away from the opening along the second direction has an inner wall. The angle between the inner wall and the cavity wall of the first channel along a third direction is greater than 90°, and the third direction intersects the first direction and the second direction respectively.

[0014] In some embodiments, the sound receiving unit includes a microphone and a circuit board. The circuit board has a communication port, and the microphone is connected to the side of the circuit board away from the sound pickup channel. The communication port extends through the circuit board in a second direction and is used to transmit sound waves entering the sound inlet from the sound pickup channel to the microphone.

[0015] In some embodiments, the difference between the distance between the center of the first pickup hole and the center of the sound inlet and the distance between the second pickup hole and the center of the sound inlet along the first direction does not exceed 0.5 mm.

[0016] In some embodiments, the distance between the center of the first pickup hole and the center of the sound inlet is equal to the distance between the center of the second pickup hole and the center of the sound inlet.

[0017] In some embodiments, the distance between the center of the first pickup hole and the center of the sound inlet is 3mm to 5mm.

[0018] In some embodiments, the distance between the center of the second pickup hole and the center of the sound inlet is 3mm to 5mm.

[0019] In some embodiments, the outer shell includes a front shell, a middle shell, and a rear shell.

[0024] The earphones provided in this application embodiment, by forming a one-piece injection-molded first pickup hole, pickup channel, and second pickup hole in the outer shell, can eliminate the need for post-shell processing, reduce manufacturing costs, and increase the appearance reliability of the earphones. Furthermore, the first pickup hole, pickup channel, and second pickup hole penetrate the outer shell along a first direction. When the earphones are worn, the first direction is parallel to the wearer's forward and backward direction. This allows airflow from outside the earphones to pass through the first pickup hole, pickup channel, and second pickup hole sequentially through the outer shell during wear. During a call, the human voice can enter the pickup channel through the first and second pickup holes, and then reach the receiving unit through the inlet. This reduces wind noise generated by airflow outside the earphones, thereby reducing the impact of wind noise on voice collection and improving call quality. Attached Figure Description

[0035] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0036] In the description of the embodiments of this application, it should be noted that the terms "upper," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0038] In related technologies, noise-canceling headphones typically have a microphone hole to collect ambient noise. This microphone hole is usually machined later, resulting in higher manufacturing costs.

[0039] Based on the above, a first aspect of this application provides an earphone 10, as shown in Figures 1 to 8. The earphone 10 includes a housing 11, a sound-emitting unit 12, and a sound-receiving unit 13. An inlet 11a is provided inside the housing 11. The sound-emitting unit 12 and the sound-receiving unit 13 are disposed within the housing 11. The sound-emitting unit 12 is disposed on the side of the sound-receiving unit 13 near the concha. The sound-emitting unit 12 is electrically connected to the sound-receiving unit 13. The housing 11 forms an integrally injection-molded first pickup hole 11b, a pickup channel 11c, and a second pickup hole 11d. The first pickup hole 11b and the second pickup hole 11d are disposed on opposite sides of the housing 11 along a first direction, for communicating with the external environment. The pickup channel 11c communicates with the first pickup hole 11b and the second pickup hole 11d along the first direction. The inlet 11a is disposed on one side of the pickup channel 11c along a second direction, for communicating with the pickup channel 11c and the sound-receiving unit 13. The pickup channel 11c is isolated from the sound-generating unit 12. The first direction intersects with the second direction.

[0040] It should be noted that the earphone 10 in this application can be a wireless earphone or a wired earphone, and can be an in-ear earphone, a semi-in-ear earphone, an open-back earphone, etc., without any restrictions.

[0041] The concha, also known as the auricular cavity or auricular depression, is part of the outer ear. Specifically, it refers to a concave area of ​​the auricle (the cartilaginous part of the outer ear) near the center of the ear. It is located between the crus of the helix and the antihelix and is a relatively open space. The concha is a prominent anatomical landmark of the auricle and plays a certain acoustic role in the structure of the ear, helping to capture and guide sound into the ear canal.

[0042] The sound-generating unit 12 is one of the core components of the earphone 10, used to convert electrical signals into sound. The sound-generating unit 12 may include a speaker or a driver, which may include a magnet, a voice coil, and a diaphragm. When current passes through the voice coil, a changing magnetic field is generated. The magnetic field interacts with the magnet, causing the diaphragm to vibrate, thereby generating sound waves.

[0043] The specific structure of the sound-generating unit 12 is not limited; it can be a moving coil type, an electrostatic type, or a planar magnetic type, etc., and there are no restrictions here.

[0044] In this application, the outer shell 11 is used to form the outer surface of the earphone 10 and to protect the internal sound-generating unit 12 and the microphone unit 13.

[0045] The sound-generating unit 12 is located on the side of the sound-receiving unit 13 closer to the concha cavity, so that the concha cavity is closer to the ear canal opening, which facilitates the transmission of audio signals from the sound-generating unit 12 to the eardrum.

[0046] The sound-emitting unit 12 is electrically connected to the sound-receiving unit 13. Here, the sound-receiving unit 13 includes a wireless transmission module. The wireless transmission module outputs an electrical signal to the sound-emitting unit 12 through electrical connection with the sound-emitting unit 12, so that the sound-emitting unit 12 outputs audio.

[0047] For example, the sound receiving unit 13 also includes a microphone 131 for collecting human voice during a call.

[0048] The outer casing 11 has an integrally injection-molded first pickup hole 11b, pickup channel 11c, and second pickup hole 11d, meaning that the first pickup hole 11b, pickup channel 11c, and second pickup hole 11d are integrally molded onto the outer casing 11. In other words, the first pickup hole 11b, pickup channel 11c, and second pickup hole 11d are not obtained through post-processing.

[0049] It should be noted that the first pickup hole 11b, the pickup channel 11c, and the second pickup hole 11d are integrally formed on the outer shell 11, which does not mean that the outer shell 11 is a one-piece structure. The outer shell 11 can be a one-piece structure or a split structure.

[0050] For example, the outer shell 11 has a split structure, and the first pickup hole 11b, the pickup channel 11c and the second pickup hole 11d can be integrally formed on one of the components of the outer shell 11, such as the middle shell 112 described below.

[0051] In other words, in this application, the earphone 10 can collect sound from outside the earphone 10 through the first pickup hole 11b and the second pickup hole 11d, and the range of sound collection is larger. On the other hand, it saves the later machining process, reduces the production cost of processing and manufacturing, and at the same time, it will not show burrs or other structures formed by machining on the surface of the outer shell 11, thus increasing the appearance of the earphone 10.

[0052] The inlet 11a is located on one side of the pickup channel 11c along the second direction, and is used to connect the pickup channel 11c with the receiver unit 13. In other words, the receiver unit 13 is connected to the outside world through the inlet 11a and the pickup channel 11c, which is beneficial for the wearer's voice to directly reach the receiver unit 13 for voice collection.

[0053] The first pickup hole 11b and the second pickup hole 11d are located on opposite sides of the outer shell 11 along the first direction and are in communication with the external environment. The pickup channel 11c connects the first pickup hole 11b and the second pickup hole 11d along the first direction, meaning that the first pickup hole 11b, the pickup channel 11c, and the second pickup hole 11d pass through the outer shell 11 along the first direction. When the earphone 10 is worn, the first direction is parallel to the wearer's front-back direction, so that when the wearer moves, the wind noise airflow outside the earphone 10 can pass through the outer shell 11 in sequence through the first pickup hole 11b, the pickup channel 11c, and the second pickup hole 11d. During a call, the human voice can enter the pickup channel 11c through the first pickup hole 11b and the second pickup hole 11d respectively, and then reach the receiving unit 13 through the sound inlet 11a. In this way, the wind noise generated by the airflow outside the earphone 10 can be reduced, thereby reducing the impact of wind noise on the collection of human voice and improving the call quality of the earphone 10.

[0054] The pickup channel 11c is isolated from the sound-generating unit 12. In other words, the pickup channel 11c and the sound-generating unit 12 are physically isolated from each other and are not connected. As a result, external dust, water vapor, etc. will not enter the sound-generating unit 12 through the pickup channel 11c. Of course, it can also block wind noise and airflow, thus improving the sealing and reliability of the sound-generating unit 12.

[0055] It should be noted that the pickup channel 11c is isolated from the sound-generating unit 12. This can be done either by isolating the pickup channel 11c from the sound-generating unit 12 during molding, or by sealing the pickup channel 11c with a sealing structure such as the sealing member 14 described below, thereby isolating the pickup channel 11c from the sound-generating unit 12. No limitation is made here.

[0056] For example, the first direction is perpendicular to the second direction.

[0057] The earphone 10 provided in this application embodiment eliminates the need for post-molding processing of the outer shell 11 by forming an integrally injection-molded first pickup hole 11b, pickup channel 11c, and second pickup hole 11d on the outer shell 11, thereby reducing manufacturing costs and increasing the appearance reliability of the earphone 10. Furthermore, the first pickup hole 11b, pickup channel 11c, and second pickup hole 11d extend through the outer shell 11 along a first direction. When the earphone 10 is worn, the first direction is parallel to the wearer's front-back direction. This allows wind noise from outside the earphone 10 to pass through the outer shell 11 sequentially via the first pickup hole 11b, pickup channel 11c, and second pickup hole 11d during the wearer's movement. During a call, the human voice can enter the pickup channel 11c via the first pickup hole 11b and second pickup hole 11d, and then reach the receiver unit 13 through the inlet 11a. This reduces wind noise generated by airflow outside the earphone 10, thereby reducing the impact of wind noise on human voice collection and improving the call quality of the earphone 10.

[0058] In some embodiments, referring to Figures 4, 6, and 8, the pickup channel 11c has an opening 11g formed on the side away from the inlet 11a along the second direction. The earphone 10 includes a seal 14. The seal 14 is connected to the housing 11 and closes the opening 11g to isolate the pickup channel 11c and the sound-generating unit 12.

[0059] The pickup channel 11c has an opening 11g on the side away from the sound inlet 11a along the second direction. This means that the pickup channel 11c can be open towards the sound-generating unit 12 along the second direction. In this way, the mold can be separated along the second direction through the opening 11g, which is beneficial for the injection molding production of the pickup channel 11c.

[0060] In this embodiment, the pickup channel 11c has an opening 11g on the side away from the sound inlet 11a along the second direction. This is beneficial for the mold to detach along the second direction through the opening 11g during the integral injection molding of the outer shell 11, which is conducive to the injection molding production of the pickup channel 11c. After the outer shell 11 is formed, a sealing element 14 is provided at the opening 11g to isolate the pickup channel 11c and the sound generating unit 12. This can improve airflow and prevent external dust and water from entering the space where the sound generating unit 12 is located, thereby improving the durability and reliability of the headphones 10.

[0061] The specific structure of the pickup channel 11c is not limited.

[0062] In some embodiments, the seal 14 is a flexible element.

[0063] For example, the material of the seal 14 includes thermoplastic polyester, such as polyethylene terephthalate (PET).

[0064] For example, the seal 14 is a PET sheet.

[0065] This facilitates the matching and installation of the seal 14 and the opening 11g, improving the assembly efficiency of the seal 14. Simultaneously, the flexible component can deform to seal and isolate the pickup channel 11c from the sound-generating unit 12, resulting in a better sealing effect.

[0066] In some embodiments, the seal 14 is adhered to the inside of the housing 11.

[0067] For example, the seal 14 is connected to the housing 11 by structural adhesive, thereby bonding the seal 14 to the housing 11 and achieving isolation between the pickup channel 11c and the sound-generating unit 12.

[0068] For example, the structural adhesive used for bonding is a soft, liquid silicone that can solidify.

[0069] This improves the sealing effect of the seal 14 at the open area and enhances the isolation reliability between the pickup channel 11c and the sound-generating unit 12.

[0070] The specific construction of the radio unit 13 is not limited.

[0071] In some embodiments, referring to Figures 4, 6, and 8, the pickup channel 11c includes a first channel 11e and second channels 11f disposed on opposite sides of the first channel 11e along the first direction. One of the second channels 11f connects the first channel 11e and the first pickup hole 11b, and the other second channel 11f connects the first channel 11e and the second pickup hole 11d. Along the second direction, the first channel 11e is larger than the second channel 11f, at least at its junction with the second channel 11f.

[0072] The sound inlet 11a is located on the side of the first channel 11e along the second direction near the sound receiving unit 13.

[0073] That is, the sound entering from the first pickup hole 11b and the second pickup hole 11d is transmitted to the first channel 11e through two second channels 11f, and then to the sound inlet 11a through the first channel 11e.

[0074] It should be noted that the size of the first channel 11e is larger than the size of the second channel 11f at least at the junction with the second channel 11f. This could mean that the size of the first channel 11e is larger than the second channel 11f at any point along the second direction, or that the first channel 11e has a portion of its size smaller than the second channel 11f along the second direction, but the size of the first channel 11e at the junction with the second channel 11f is larger than the size of the second channel 11f.

[0075] For example, the second direction is perpendicular to the plane containing the auricle.

[0076] It should be noted that the dimension of the first channel 11e in the second direction can remain unchanged or change. Similarly, the dimension of the second channel 11f in the second direction can also remain unchanged or change. The change can be a gradual increase or decrease, or a step change, such as a step-by-step increase or decrease; no restrictions are placed here.

[0077] In this embodiment, the second channel 11f can guide the airflow, guiding the airflow from the first pickup hole 11b and the second pickup hole 11d into the first channel 11e or from the first channel 11e toward the first pickup hole 11b and the second pickup hole 11d. The size of the first channel 11e is larger than that of the second channel 11f at least at the junction with it. This can slow down the flow rate of the wind noise airflow when it enters the first channel 11e, thereby reducing the impact of the wind noise airflow in the first channel 11e on the sound inlet 11a.

[0078] In some embodiments, referring to Figures 4 and 6, an opening 11g is formed on the side of the first channel 11e away from the sound inlet 11a along the second direction. The side of the first channel 11e away from the opening 11g along the second direction has an inner wall 11h. The angle between the inner wall 11h and the cavity wall of the first channel 11e along the first direction is greater than 90°.

[0079] For example, the angle between the inner wall 11h and the cavity wall of the first channel 11e along the first direction is 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99° or 100°, etc., and is not limited here.

[0080] As shown in Figure 6, the angle between the inner wall 11h and the cavity wall of the first channel 11e along the first direction is represented by α.

[0081] For example, the sound inlet 11a is formed on the inner wall 11h.

[0082] Here, the two second channels 11f are formed by demolding outward along the first direction through the first pickup hole 11b and the second pickup hole 11d respectively through the mold, and the first channel 11e is formed by demolding outward along the second direction away from the inner wall 11h through the opening 11g of the mold, which is beneficial to the integral molding and manufacturing of the pickup channel 11c.

[0083] In this embodiment, the angle between the cavity wall of the first channel 11e on one or both sides along the first direction and the inner wall 11h may be greater than 90°. In this way, when the mold is demolded through the opening 11g along the second direction toward the side where the sound-generating unit 12 is located, the cavity wall of the first channel 11e on one or both sides along the first direction has a demolding angle, which is more conducive to the separation of the mold from the cavity wall of the first channel 11e along the first direction.

[0084] In some embodiments, referring to Figures 4, 7, and 8, an opening 11g is formed on the side of the first channel 11e away from the sound inlet 11a along the second direction. The side of the first channel 11e away from the opening 11g along the second direction has an inner wall 11h. The angle between the inner wall 11h and the cavity wall of the first channel 11e along a third direction is greater than 90°, and the third direction intersects the first direction and the second direction, respectively.

[0085] For example, the angle between the inner wall 11h and the cavity wall of the first channel 11e along the third direction is 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99° or 100°, etc., and is not limited here.

[0086] It should be noted that the third direction can be the length direction of the earphone 10.

[0087] It should be noted that the dimensions of different parts in the three directions are different in the same absolute coordinate system. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0088] As shown in Figure 8, the angle between the inner wall 11h and the cavity wall of the first channel 11e along the third direction is represented by β.

[0089] In this embodiment, the angle between the cavity wall of the first channel 11e on one or both sides along the third direction and the inner wall 11h may be greater than 90°. In this way, when the mold is demolded through the opening 11g along the second direction toward the side where the sound-generating unit 12 is located, the cavity wall of the first channel 11e on one or both sides along the third direction has a demolding angle, which is more conducive to the separation of the mold from the cavity wall of the first channel 11e along the third direction.

[0090] In some embodiments, the angle between the cavity wall of the first channel 11e along the first direction and the cavity wall of the first channel 11e along the third direction and the inner wall 11h is greater than 90°. In this way, the mold has a demolding angle in both the first direction and the third direction, which is more conducive to the separation of the mold from the cavity wall of the first channel 11e along the first direction and the third direction, and is conducive to one-piece injection molding production.

[0091] It is understandable that, since the angles between the cavity wall of the first channel 11e along the first direction and the cavity wall of the first channel 11e along the third direction and the inner wall 11h are respectively greater than 90°, the angle between the cavity wall of the first channel 11e along the first direction and the cavity wall of the first channel 11e along the third direction will also be greater than 90°, for example, it can be 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99° or 100°, etc., without limitation.

[0092] In some embodiments, referring to Figures 6 to 8, the sound receiving unit 13 includes a microphone 131 and a circuit board 132. The circuit board 132 is provided with a communication port 132a. The microphone 131 is connected to the side of the circuit board 132 away from the sound pickup channel 11c. The communication port 132a extends through the circuit board 132 in a second direction. The communication port 132a is used to transmit sound waves entering the sound inlet 11a from the sound pickup channel 11c to the microphone 131.

[0093] Microphone 131 is connected to the side of circuit board 132 away from the sound pickup channel 11c. That is, microphone 131 and circuit board 132 are located on the side of sound pickup channel 11c away from the sound-generating unit 12. The connecting port 132a on circuit board 132 is connected to the sound inlet port 11a and microphone 131 respectively, so that the sound waves entering the sound inlet port 11a from the sound pickup channel 11c are transmitted to microphone 131.

[0094] For example, the radio unit 13 also includes a buffer 133, which is disposed between the circuit board 132 and the sound inlet 11a and covers the sound inlet 11a. The buffer 133 can transmit sound waves and can block airflow, dust and impurities in the airflow to a certain extent, which helps to protect the radio unit 13.

[0095] For example, the buffer 133 is a mesh fabric.

[0096] In this embodiment, by setting a connecting port 132a and a microphone 131 at the location of the sound inlet 11a and on the side of the sound pickup channel 11c away from the sound-generating unit 12, sound waves can pass through the sound pickup channel 11c, the sound inlet 11a, and the connecting port 132a in sequence to directly reach the microphone 131, thereby enabling the microphone 131 to collect human voices. The sound wave flow path of the sound pickup channel 11c, the sound inlet 11a, and the connecting port 132a is perpendicular to the flow path of the wind noise airflow along the first direction, which improves the impact of the wind noise airflow impact on the front of the sound inlet 11a and can improve the clarity of human voice collection.

[0097] In some embodiments, referring to FIG6, the difference between the distance between the center of the first pickup hole 11b and the center of the sound inlet 11a and the distance between the center of the second pickup hole 11d and the center of the sound inlet 11a along the first direction does not exceed 0.5mm.

[0098] It should be noted that, as shown in Figure 6, the distance between the center of the first pickup hole 11b and the center of the inlet 11a is represented by D1, and the distance between the center of the second pickup hole 11d and the center of the inlet 11a is represented by D2.

[0099] It should be noted that the distance D1 between the center of the first pickup hole 11b and the center of the inlet 11a and the distance D2 between the center of the second pickup hole 11d and the center of the inlet 11a can be equal or unequal.

[0100] For example, the difference between the distance D1 between the center of the first pickup hole 11b and the center of the sound inlet 11a and the distance D2 between the second pickup hole 11d and the center of the sound inlet 11a is 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm, etc., and is not limited here.

[0101] In this embodiment, the positional deviation of the first pickup hole 11b and the second pickup hole 11d relative to the center of the sound inlet 11a is small, that is, the travel distance of the sound from the first pickup hole 11b into the sound inlet 11a is equal to or the difference is small with the travel distance of the sound from the second pickup hole 11d into the sound inlet 11a, thereby increasing the consistency of sound pickup.

[0102] In some embodiments, please refer to Figure 6, the distance between the center of the first pickup hole 11b and the center of the sound inlet 11a is equal to the distance between the center of the second pickup hole 11d and the center of the sound inlet 11a.

[0103] In this embodiment, the travel distance of sound from the first pickup hole 11b into the sound inlet 11a is equal to the travel distance of sound from the second pickup hole 11d into the sound inlet 11a. When the microphone 131 collects sound signals from the first pickup hole 11b and the second pickup hole 11d respectively, the consistency is high, which improves the microphone 131's sound collection effect.

[0104] In some embodiments, please refer to Figure 6, the distance D1 between the center of the first pickup hole 11b and the sound inlet 11a is 3mm to 5mm.

[0105] For example, the distance between the center of the first pickup hole 11b and the center of the sound inlet 11a is 3mm, 3.2mm, 3.5mm, 3.8mm, 4mm, 4.2mm, 4.5mm, 4.8mm or 5mm, etc., and is not limited here.

[0106] This helps to minimize the size of the headphone 10 in the first direction while improving the reduction of wind noise airflow entering the pickup channel 11c from the first pickup hole 11b.

[0107] In some embodiments, please refer to Figure 6, the distance D2 between the center of the second pickup hole 11d and the sound inlet 11a is 3mm to 5mm.

[0108] For example, the distance between the center of the second pickup hole 11d and the center of the sound inlet 11a is 3mm, 3.2mm, 3.5mm, 3.8mm, 4mm, 4.2mm, 4.5mm, 4.8mm or 5mm, etc., and is not limited here.

[0109] This helps to minimize the size of the headphone 10 in the first direction while improving the reduction of wind noise airflow entering the pickup channel 11c from the second pickup hole 11d.

[0110] The specific structure of the outer shell 11 is not limited.

[0111] In some embodiments, referring to Figures 1 to 7, the outer shell 11 includes a front shell 111, a middle shell 112, and a rear shell 113. The middle shell 112 has a first opening 112a and a second opening 112b on opposite sides along a second direction. The front shell 111 is connected to the side of the middle shell 112 along the second direction near the concha cavity and closes the first opening 112a. The rear shell 113 is connected to the side of the middle shell 112 along the second direction away from the concha cavity and closes the second opening 112b. A sound-generating unit 12 is disposed within the space enclosed by the front shell 111 and the middle shell 112. A sound-receiving unit 13 is disposed within the space enclosed by the middle shell 112 and the rear shell 113. A first pickup hole 11b, a pickup channel 11c, and a second pickup hole 11d are integrally formed on the middle shell 112.

[0112] The middle shell 112 has a first opening 112a and a second opening 112b on opposite sides along the second direction, so that the mold core can be demolded from the first opening 112a and the second opening 112b respectively, which is beneficial to the integral injection molding of the middle shell 112.

[0113] The front shell 111 is connected to the middle shell 112 along the second direction near the concha cavity and closes the first opening 112a, thereby protecting the sound-generating unit 12 disposed in the space enclosed by the front shell 111 and the middle shell 112.

[0114] The rear shell 113 is connected to the side of the middle shell 112 away from the concha cavity along the second direction and closes the second opening 112b, thereby protecting the radio unit 13 disposed in the space enclosed by the middle shell 112 and the rear shell 113.

[0115] In this embodiment, the first pickup hole 11b, the pickup channel 11c, and the second pickup hole 11d are integrally formed on the middle shell 112. The first opening 112a of the middle shell 112 is then closed by the front shell 111, and the second opening 112b of the middle shell 112 is closed by the rear shell 113, which is beneficial for production and assembly.

[0116] For example, the middle shell 112, the front shell 111 and the rear shell 113 can be integral injection molded structures. When the middle shell 112 is formed, the first pickup hole 11b, the pickup channel 11c and the second pickup hole 11d are formed. Then the middle shell 112 is fitted with the sound receiving unit 13 and the sound generating unit 12. Then the outer shell 11 is fitted with the middle shell 112. Finally, the rear shell 113 is placed on the side of the middle shell 112 away from the concha cavity along the second direction.
